Possible Solutions
Verify that both ends of the twisted pair
cables use 568B crimp pattern.
Swap the twisted pair cables in the AV and
HDCP RJ45 inputs on the receive balun.
Verify the power supply is connected to
either the send or receive balun.
Verify the power LEDs on both the send
and receive units are brightly illuminated.
Power off the destination device and power
it back on to force renegotiation.
Unplug and re-plug the HDMI cable from
receive balun to force renegotiation.
Use shorter runs of twisted pair cabling.
Drop the HDMI signal to the next lower
resolution; i.e., decrease resolution from
1080i to 720p, etc.
Replace the twisted pair cable with a
higher grade twisted pair cable; i.e.,
replace Cat 5e with Cat 6.
If the destination device is incapable of
displaying the video signal, alter the source
signal; i.e., decrease resolution from 1080i
to 720p, etc.
Change source device to output PCM other
than Bitstream audio
Enable PCM down sampling if supported
by your source device
